Inflationary Constraints on String Theory
Speaker(s): Mark Hertzberg
Abstract: It is an important task to embed inflation in a fundamental microphysical theory such as string theory. Since string theory possesses a vast landscape of 4-dimensional theories, we would like to know which portions contain inflation and which do not. I prove a no-go theorem that inflation and de Sit... read more

Gravitational wave background as a probe of reheating temperature of the Universe
Speaker(s): Kazunori Nakayama
Abstract: 'Thermal history of the universe after big-bang nucleosynthesis (BBN) is well understood both theoretically and observationally, and recent cosmological observations also begin to reveal the inflationary dynamics. However, the epoch between inflation and BBN is scarcely known. In this work we show t... read more

Flaxino dark matter and stau decay
Speaker(s): Kazunori Kohri
Abstract: If the spontaneous breaking of Peccei-Quinn symmetry comes from soft supersymmetry breaking, the fermionic partners of the symmetry-breaking fields have mass of order the gravitino mass, and are called flatinos. The lightest flatino, called here the flaxino, is a CDM candidate if it is the lightest ... read more

Non-Anticommutative supersymmetry in two dimentions
Speaker(s): Ian Jack
Abstract: We formulate non-anticommutative supersymmetry in two dimensions using differential operators acting on the component fields. We then use these operators to give a compact expression for the one-loop divergences in the non-anticommutative Kahler sigma model.

The subhalo population of the MW: open questions
Speaker(s): Lidia Pieri
Abstract: The smaller Dark Matter structures predicted in the CDM scenario have a mass in the range [10e-12;10e-4] Msun, depending on the underlying particle physics. It is however not clear what is the inner DM structure of such halos, nor which is the real survival probability during mergers. We show how th... read more

The Fragility of Higgs Boson Predictions for the LHC
Speaker(s): James Wells
Abstract: The Higgs boson is the only scalar particle in the Standard Model. Precision electroweak analyses suggest that it should be light -- less than 200 GeV. These facts combined with the speculative nature of all electroweak symmetry breaking discussions imply significant uncertainty in discovering a Hig... read more

Lattice Gauge Theory in the LHC Era
Speaker(s): Paul Mackenzie
Abstract: Lattice QCD in this decade has succeeded in producing essential results for crucial components of Standard Model phenomenology such as constraints on the rho-eta plane. Much more will be required of lattice gauge theory in the LHC era: sub-per cent precision in QCD quantities and the ability to calc... read more
